2. In which processes does the metal removed is negligible?Explanation: During the metal removal process, more metal is removed (not negligible), but Metal removal in surface treatments can be ignored.

Which process has the highest metal removal rate?

Discuss

• The metal removal rate for electrical discharge machining (EDM) is approximately 10-20 mm3/s.
• Electrochemical machining (ECM) has the highest metal removal rate, around 200-300 mm3/s.
• The metal removal rate for ultrasonic machining (USM) is approximately 5-10 mm3/s.

Which of the following craft tools has negligible wear?

Explanation: in ECM, there is no mechanical contact between the workpiece and the tool, so there is no possibility of tool wear. Using Faraday’s law of electrolysis, material is removed from the workpiece by the chemical action of the electrolyte.

What is the process of removing metal?

A material removal process is a manufacturing process in which the final product is obtained by removing excess metals from raw materials.a best example Processing Cylindrical surfaces are generated from metal stock with the help of a lathe.

Which of the following processes has the lowest metal removal rate?

Which of the following processes has the lowest metal removal rate? explain: Honing It is a surface finishing operation and therefore has a low metal removal rate.

What is an EDM tool?

EDM is A thermoelectric process used to remove metal through a series of discrete sparks between the metal and the workpiece. In EDM, EDM is used as a cutting tool to cut (erode) the workpiece and machine the finished part into the desired shape. … the workpiece is usually the anode and the tool is the cathode.

Why is titanium machining difficult?

However, the machinability of titanium alloys is difficult because they Low thermal conductivity and elastic modulus, high hardness and high chemical reactivity at high temperature. The influence of titanium properties on machinability is also highlighted.

What is the difference between reaming and tapping?

reaming is a cut Operate with multi-edged knives that are constantly in action. Holes with high dimensional accuracy and surface finish can be produced. Tapping is a cutting operation using a multi-blade tool (tapping). Tapping provides a threaded hole as a non-permanent joint.

Is titanium more expensive than gold?
